guys any one know that if there will be a deduction of mark if we directly solve quadratic equation from the calculator and just write down the answer without showing our steps

for 11ii
take the area under line graph.... it will give u all the area under graph shaded + unshaded
take area under curve by integrating the curve equation (gives unshaded are)
subtract the two
no i know the formulae i know the limits
but my answer is comming wrong idk y ?
yeah but in (ii) It's asking about a different equation , not the one i already sketched. and it's for one mark , do i have to sketch that as well?For the first part you HAVE to sketch .. The. State the number of solutions .. Let's say 2
So then you check the other question it says upto 20pie but u have till 0-2pie .. So u consider o-2pie as one revolution and then count number of revolutions u need .. Till 20 pie it will be around 10 maybe .. And u have for one resolution 2 solutions so for 10 resolutions .. Just multiply
guys this might helpAssalamoalaikum Wr Wb!
Post your doubts here. Make sure you give the link to the question paper when posting your doubts.
May Allah give us all success in this world as well as the HereAfter...Aameen!!

You better show your working, in every thing.guys any one know that if there will be a deduction of mark if we directly solve quadratic equation from the calculator and just write down the answer without showing our steps
for 7(iii)
f(x)=(x-2)^2+3
f=hg
h(g(x))=(x-2)^2+3
h(g(x))=(g(x))^2+3, take g(x)=x
h(x)=x^2+3
Thank you very much.. But I dont understand why you took g(x)=x
Prove the identity (sin x + cos x)(1 − sin x cos x) ≡ sin3 x + cos3 x. [3]thnakkks
(i) f(x)=x^2-4x+7http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w10_qp_12.pdf
hey has anyone answered this question 7 from this paper cz i forgot if u did can u guyss explain it to me esp the last part or if u have already done that then just tell me where u did that thnx
I tried my best to understand, but it is hard. I found this.
